1. The problem statement, all variables and given/known data hey everybody i got a problem but do not know how to do it, A 2.0 kg frictionless cart is moving at a constant speed of 3.0m/s to the right on a horizontal surface. it then collides with a mass that is at rest. as a result the cart acquires a speed of 1.6m/s. Neglect friction. Caluclate magnitude and direction of the velocity of the 2.0 kg cart after the collison Calculate mass of the second cart. 2. Relevant equations Im not sure what equations i need to use so thats why i am here. 3. The attempt at a solution No idea of how to solve please help thanks alot.
